Is one better than two ?
 

Hello everybody . this is my first post so hopefully i won't bore u by asking dumb questions :)
I have planned to construct my own homemade water cooling kit .. so i gathered all the information from various websites including this one about the main concept of watercooling .. and the following items are which i have gathered till now .

1 - 4 copper blocks ( 99% copper ) , each one for the cpu , gpu , hard drive and chipset cooling

2- one Boyo water pump ( 500 gallon per hour )

3- tubings and tightners

4- A reservoir ( using my thermos :P )

5 - Distilled water ( of course ) and some anti freezing agent

Well for the cooling .. i have 2 options i.e

1 - get a used toyota 92 radiator without fan to use it with my pc for kick ass cooling ( which is available at the motor shop for equivalent 20 $ ) .

2- or get a simple heatcore and mount a big fan on it

which one is better ? i have i have checked at many forums and im kinda confused . Some say the radiator is better as it has large copper tubes as compared to the tiny heater core so heat dissapates faster providing long cooling solution and u dont even have to mount a fan on it.
While some say heatercore are better cause they dont cause blockage or disturbance in the flow of water .
If i should go for the heatercore .. would using two heatercore in one water cooling system would give me some cooling advantage over using just a single one ? :shrug:
Btw im constructing this for my athlon 64 3000+ cpu with dfi lanparty ut nf3 and ati radeon 9800 pro .
As for the water blocks .. i will be trying to contruct a similar one as a d-tek white water using the specific design and will see if i can make a little white water for my gpu as well . the dangerden maze 4 is real hard to make . Thanks a lot . CHEERS ! :p

When it comes to radiators (heatercores), airflow is critical.

My buddy Rosco recently wrapped a Zalman reserator then stuck a fan on top of it; the temps dropped ~10 degrees.

Any fan is a good fan.

well ok ... this means i should buy a heatercore instead of a radiator . So .. should i go use two heatercores in the water cooling setup ? will it give more low temperatures and extra cooling as compared using only one heatercore ? Btw thanx for ur reply bigben :)

If you dont mind the size of a full car radiator by all means do it. Put it infront of a window fan or something and with very little air flow Im sure its C/W would be pretty darn low. But thats a lot of fluid and a lot of size to work with. Definitely post pics if you do it :D
Someone here has an all copper civic radiator with like 9 120mms on it. If thats the route you want to go Id search for that thread.
